637aa617 - [ARM] Fix VBICimm and VORRimm generation under Big endian. (#107813)

[ARM] Fix VBICimm and VORRimm generation under Big endian. (#107813) This is a smaller follow on to #105519 that fixes VBICimm and VORRimm too. The logic behind lowering vector immediates under big endian Neon/MVE is to treat them in natural lane ordering (same as little endian), and VECTOR_REG_CAST them to the correct type (as opposed to creating the constants in big endian form and bitcasting them). This makes sure that is done when creating VORRIMM and VBICIMM.
